Consider removing blas_scipy.py

1

This file includes an alternative `Ger` `Op` that goes through scipy when in Python mode. This seems unnecessary, We have many more such routines implemented in `blas.py`, and it seems...

Add ARM dev environment dependencies

2

The `environment-arm.yml` file is a copy of `environment.yml` with Intel MKL dependencies replaced with OpenBLAS. We may want to update the documentation on installing `aesara` on Mac OS or complete...

Intel MKL FATAL ERROR upon importing Aesara on M1 Mac

4

Importing Aesara yields the following error due to the `mkl` package. Recreating the conda environment in [`environment.yml`](https://github.com/aesara-devs/aesara/blob/main/environment.yml) minus the [`mkl` dependencies](https://github.com/aesara-devs/aesara/blob/main/environment.yml#L20-L22) allows Aesara to be imported. Given that `mkl` is...

Add string types

Remove "exercises" and "solutions" from the documentation

1

There are a few places in the documentation with "exercises" and "solutions" (e.g. [here](https://aesara.readthedocs.io/en/latest/tutorial/loop.html)). We don't need that form of presentation, so let's remove it.

Overhead in `Scan` when sampling

13

Apparently, use of updates for random sampling within a `Scan` can be quite costly. The following illustrates: ```python import aesara import aesara.tensor as at from aesara.ifelse import ifelse import numpy...
